Abstract: Surface morphology, surface material, greenery, anthropogenic heat and air pollutants are known as the elements that determine the thermal environment performance. These elements, hence, should determine the outdoor thermal comfort level. However, previous studies mentioned that the role of psychological adaptation in outdoor thermal comfort is greater than in the indoor. Therefore, exploring perceived elements, which determine the thermal environment, could enrich the perspective of a design approach of thermally comfortable open spaces. This study aims to explore the perceived elements of thermal environment, which contribute to the outdoor thermal comfort using open-ended questions of an online questionnaire. Several keywords obtained by the content analysis of 101 respondents’ answers affirm the role of the thermal environment elements in modifying the thermal environment. Tree or greenery, the most frequently appeared keyword, showed as the strongest perceived element. New keywords that significantly appeared; i.e. visual aspects, supporting facilities, and tranquility; indicate the importance of thermo-spatial perception approach in designing livable and thermally comfortable outdoor environment.

Keywords: elements of thermal environment, outdoor thermal comfort, perception, psychological adaptation,

Abstraksi: Morfologi permukaan, permukaan material, area hijau, panas antropogenik dan polutan udara diketahui sebagai elemen-elemen yang menentukan performansi lingkungan termal. Dengan demikian, elemen-elemen tersebut seharusnya menentukan tingkat kenyamanan termal outdoor. Namun, beberapa studi menyebutkan peranan adaptasi psikis pada kenyamanan termal outdoor yang lebih besar dibandingkan pada kenyamanan termal indoor. Oleh karenanya, eksplorasi elemen-elemen yang dipersepsikan menentukan lingkungan termal dapat memperkaya perspektif pendekatan studi ruang terbuka yang nyaman secara termal. Studi ini bertujuan untuk menggali elemen-elemen lingkungan termal yang dipersepsikan berperan pada kenyamanan termal outdoor dengan menggunakan pertanyaan-pertanyaan yang bersifat open-ended di dalam kuesioner online. Beberapa kata kunci yang dihasilkan oleh analisis konten dari 101 responden mengkonfirmasi peranan elemen-elemen lingkungan termal di dalam memodifikasi lingkungan termal. Pohon atau greenery, kata kunci yang paling sering muncul, menunjukkan sebagai elemen yang dipersepsikan paling kuat. Kata kunci baru yang muncul secara signifikan, yaitu: aspek visual, fasilitas penunjang, dan ketenangan; mengindikasikan pentingnya pendekatan persepsi termo-spasial di dalam merancang lingkungan outdoor yang hidup dan nyaman secara termal.

Kata kunci: adaptasi psikis, kenyamanan termal outdoor, persepsi, unsur-unsur lingkungan termal
